Home Entertainment Suppliers (HES) is an Australian company that distributes video games and accessories. HES ported over various games to the Nintendo Entertainment System(NES) for companies such as American Game Cartridges, American Video Entertainment (AVE), Bit Corp, Color Dreams, Epyx, Thin Chen Enterprise (Sachen, Joy Van, etc.) and Tengen as unlicensed titles. Back in the late 1980s and early 1990s HES has a reputation for distributing unlicensed NES games at a discounted price but these days those once dirt cheap games are worth a lot of money to collectors due to their limited numbers when they were first released. As expected Nintendo weren’t pleased about these unlicensed games being sold for their system so they introduced the “Nintendo Seal of Quality” logo that’s featured on all licensed games, HES then started adding their own logo to the packaging of their games that looked similar to the Nintendo version. This was most likely done to confuse potential buyers, the HES logo reads “H.E.S. cartridge for Nintendo Use with a Nintendo Cartridge. (Instructions enclosed)”. To further combat against unlicensed games being played on the NES Nintendo made revisions to the hardware of later model NES units to block the use of these games, that’s why some HES games won’t work on later NES models. HES later made their game cartridges with a built in bypass system that requires users to insert another official NES game into the HES game cartridge, this system is referred to as ‘Piggy Back’ or ‘Dongle’ games.
